LC86G - High consumption in BACKUP mode

IoT Modules GNSS Module
1

I’m using the LC86GAB. When I send the command “$PAIR650,0”, my module enters sleep mode, but the overall system consumption remains around 1 mA because of it (I confirmed this through measurements).

The method I used is the same as shown in the photo, so I was expecting something around 50 µA for the entire system…

Hi Samuel,

Did you disable VCC power supply? If VCC is running during sleeping mode, there will be extra power consumption.

Best regards
